I'm not speculating about why they aren't criminals, or even whether or not they should be criminals, only that unless they break the law, they aren't criminals, by definition. To put it another way, lobbying is not illegal, therefore the fruit of the lobbying, to make something legal that should not be, is also therefore allowed. But this (roughly speaking, campaign finance reform) is another issue that, like white collar crime, is too abstract to produce outrage, and therefore, too weak to produce enough votes for change (as Bernie discovered).
